Welcome to All Things Plants, Ginny @Desma83
I agree with Tom -- they look like they may have been overwatered. Those plants should be much more vigorous after 2 months. I've never grown my squash in containers, but I start the seeds in pots 2-3 weeks before I plant them out and the transplants actually look healthier than your plants do right now. Growing in containers is actually much trickier and less forgiving than growing in the ground, so experience will be your best teacher! Whatever else you do, don't just water every day no matter what... check the soil for moisture first, or if the plant is wilting then you definitely need to water. And also definitely make sure there are plenty of drainage holes in your container.
Also, what sort of soil or potting mix do you have in the container?
Even those of us who have been gardening for many years find there are lots of new things still to learn... as a new gardener it may seem a bit overwhelming at times, but celebrate your successes and learn from the failures, and most of all, have fun!
