I have a line of about 5 heads. The ones farthest away from the valve
are working perfectly. The 3 closest to valve only go part way up and if
I manually pull them up, they often stay up even after the water is
turned off.
The farther ones working would tend to argue against pressure
issues. Does it seem the best idea to just replace those three or is
there some other diagnostic trick I should try first?

Try spraying them with some silicone lube, while they are full up.

I'd pull the spray tip off first, and inspect the plastic cone type
filter. Remove those three, the cone and run the zone to flush out
any debris, grit or pebbles.

Later, consider replacing the three pop-ups, the springs have worn
out. Salvage some parts for future adventures G.

Swap them. See if the problem moves with the heads or follows the location.

+1 Reduce the friction. Yet, sprinkler pop-ups wear out (often the
spring).

Replace one and if that fixes it, replace the other two.

Save the old ones in case I'm wrong. Maybe they can be cleaned,
although I guess if so, you should do that before buying new ones. Not
that I've ever cleaned one, but dirt is the biggest problem for almost
anything mechanical.

I have already done that. Sorry forgot t tell you.

Take them apart and clean them out. Buy new if they still don't pop up.

For $5-6 bucks each it seems just as easy to and probably quicker to
just get new. Wouldn't I have to dig them out and take them off the line
to take them apart and clean them? (Serious question, BTW)

On mine, the head unscrews...pull it up, unscrew head.

When mine start sticking, I pull out the grass blocking their movement.
Then turn on the water, and repeatedly push the head down and let it pop
back up. Water squirts out along the sides in the process, and tends to
wash out grit that is making them stick.
