They look fine but it's hard to say how they're doing overall as you don't say how old they are. If they're 14 days or so they're doing great, if it's been 28 days then there's something going on that's stunting them or slowing their growth. I'm personally not a big fan of those cups. At least I don't like burying the cup and letting the roots grow through it. Take the root ball out of the cup before you transplant unless they have grown into the actual cup. If they're stuck inside those cups I'd cut the bottom inch off with a scalpel or sharp knife and then bury it. Best of luck on your grow.
