As spaghetti squash is a Cucurbita pepo and a banana squash is a Cucurbita maxima, they will not cross. Only cucurbits within the same species will cross-pollinate so you can grow one of each. Incidentally, the fruit of crossed species is still edible, but often inferior.
yes you cook them just like pumpkin seeds
The spaghetti squash is a winter (hard skinned) squash.
Squash is a vegetable, spaghetti is pasta which is not a vegetable. It's starch.
Spaghetti squash has fibrous strands inside it that can, when cooked, be used as a substitute for pasta. Spaghetti squash is a harder-shell squash, like a pumpkin, rather than a softer squash like a zucchini.
it is summer spaghetti squash.
Gourds are edible, about like a squash.
I have an interesting and rather weird-looking hybrid growing in my compost pile right now. It appears to be a cross between a small sugar pumpkin and a spaghetti squash. This makes sense, because spaghetti squash is technically a kind of pumpkin. It has 3 fruit on it: They are mostly yellow (like spaghetti squash) but with green bottoms (like an unripe pumpkin). They are almost cylindrical in shape with nearly flat bottoms. I am not sure if I will be adventurous enough to cook one, but I will definitely cut into it and see if it has a spaghetti-like flesh! Anyway, the general answer to your question is yes, if they are from the same botanical species, but otherwise, no.
A spaghetti squash weighs in that range.

Spaghetti squash is ready to harvest when the color is uniform and the shell is hard. Try to "cut" the squash with your fingernail. If it doesn't go in, the squash is ripe and ready to use. It should be hard to cut in half.
One is able to prepare spaghetti squash in several ways, one can chop it up or leave it whole and then put it in the microwave, oven, or stove and cook the squash until it is tender.
