I think I'll try to contribute for Lucas.
Carry - 1/2
Lucas can't carry at all. All of his moves have too much ending lag (even though all non-smashes have quick startup) and they all lack range. His matchups are horrible and he just simply can't survive in 2v1.
Tank - 8 or 10 or 11
Lucas has a good and quick recovery such that he can recover from anywhere provided that he has his double jump. His teammate will seldom ever be in a 2v1 situation while he's offstage; the person would be trying to gimp PKT2 when he gets the chance lol. He also has quick aerials and PK Fire to deter any ledgeguarders and allow for a safe recovery back to the stage. Zapjumps, combined with wavebouncing and magnet pull, add that to his tether gives Lucas a diverse and quick recovery that is hard to predict and harder to gimp.
However, he is only a slight bit lighter than Mario and therefore doesn't have much surviving capability when facing people with good knockback moves. His aerials are slow in general (Nair lasts 45 frames and is his fastest) and therefore he doesn't have much momentum cancelling capability. His hurtbox is average-sized and isn't particularly small so isn't that hard to kill overall.
The reason I listed this as 8 or 10 is because he's 10 when with a good cleric like Lucario or ZSS or Pikachu, and 8 when without. I guess you can consider him to be a 9 when with a pseudo cleric; absorbable projectiles with minor health gain like Pit or Falco. As long as the Lucario/ZSS/Pikachu survives and stays, Lucas has an infinite health and it is very well possible for the Lucas to be at a stock advantage when the healing is done correctly. Magnet-Cancelling makes it very hard for the opponent to hit Lucas while he is healing. (On another note, this is what sets Lucas and Ness apart from G&W; G&W's bucket, on absorption, has a ton of lag and can easily be hit by a killer while he's absorbing while Ness and Lucas can simply cancel their magnets).
When paired with a Zamus, Lucas is an 11 in tank. Her downsmash heals 23% and lasts a total of 33 frames; it's spammable and heals 46% per second. Lucas can go down from 100% back to 0% in the time it takes for an edgeguarded opponent(s) to get back.
Punisher - 10
What can I say? Fsmash kills at around 110-120% undecayed with proper DI and comes out in 14 frames. The jablock works starting at 70% with most characters and is a guaranteed death should it land (and they fail to tech). Any opponent makes a mistake, they're dead. Did Jigglypuff whiff a Rest, or did ZSS miss a grab? Usmash kills at 90% undecayed with proper DI, and comes out on the 29th frame. Lucas' ally can hit lucas with a weak move like a jab/falco laser/pit arrow to negate all ending lag of Lucas' moves. Any opponent must be wary with laggy moves when facing a team with a Lucas.
DPS - 8/9
Lucas' DPS isn't that bad. His aerials are quick and all of them do at least 12% damage (excluding Bair, but that goes unused most of the time). His tilts are also quick and with the exception of dtilt (lol dtilt), also do at least 11% damage. Lucas has decent comboes when the opponent is at a low percentage and with proper support from another DPS teammate, his ability as a punisher kicks in.
Support - 8
Lucas has great offensive support. Usmash and Fsmash both give grab-releases that extra kick in terms of scaring and threatening the opponent. If the Lucas knows what he's doing, a D3 downthrow could well lead to a Usmash at killing percentages.
As for defensive support, he's pretty decent. He has a 2-frame jab that can get his ally out of a tight snitch pretty fast. His air speed and ground speed are both above average, and all of his aerials except Bair come out on the 4-5th frame. Tilts are also really fast.
However, his interference is pretty high. All his special moves sans PSI Magnet are all projectiles, therefore they can interfere with his ally and **** something up pretty bad. His Usmash has incredible range and lasts pretty long and killing your ally with it isn't something too rare if the opponent knocks Lucas' ally into it/the ally happens to be there.
His best teammates stem from his magnet. The Lucas boards have a consensus on Ness and ZSS and G&W (three of Lucas' specials are bucketable). I personally also find Lucario to be a good support because of DPS and his good Carry ability, and as long as Lucario has an aura sphere charged, Lucas can have a free 30% whenever he wishes. As mentioned above, ZSS's down smash heals 23% and lasts 33 frames. The hitbox also stays out (unlike other projectiles) and can still hit enemies, which means it just makes Lucas that much more tanky.
Dedede is also an excellent partner. Down-throw's set knockback makes Lucas' smashes that much more formidable. He also handles Lucas' bad matchups pretty well and has great damage racking capabilities.
