It’s not too cold, but growth would be faster if it were warmer at night, and RH was higher during daytime

Yep this.
Also Too high rh at night or big swings in general is a recipe for pm and mould too so be careful.
Only time is get to 68f when lights off for 4hours would it be best to leave lights on 24 hours n what he you recommend cause I can raise it if need be
Will this damage plant?

Yea those two are fine. Warmer plants grow faster. Putting a clear dome over them should increase temp a couple degrees, and increase RH, which seedlings like.
24/0 will not hurt them. People do it all the time

No, people do it all the time during veg. If temp is a problem I'd do it.

Why haven't you planted them yet?
I plant my rapid rooters as soon as they sprout so the tap root can grow downward.

Plant them all, the runts might surprise you and catch right up to their bigger sisters....worst case scenario they dont and you bin them. No loss

Now you have a plan to increase veg growth and inhibit mold.
Most growers would flip to 12/12 after a month or more. When you do in January or February it’s going to be even colder in the tent. Plan now for adding heat at night and lowering RH. A dehumidifier will do both effectively. Bring RH to 35-40% late in flower. Go an extra day between waterings. Make her produce her own moisture!
When shopping dehumidifiers check operating temperature range - some freeze up when it’s cold.

I usually wait to flip at around 15". They will stretch quite a bit during flower, so depending on how powerful your light is, if they get to tall the light won't penetrate very far. I topped and lst'd my last one for the first time using a CMH 315 light with pretty good success. You might consider that when you get to that point.
I have two seeds left I’m thinking of just planting them n see if they do better then the runts
Temps stays at 80f with lights on 24/7. I also have a small heater if the temps drop due to the winter
