Yes it is. I fed it a gnat earlier today. I watched another vid online but still unsure how to proceed with this specific plant. It seems the leaves are very small, much smaller than the ones on the pics and video I've seen so far. I've also noticed some of the leaves seem to have shut on their own.

VFTs will have several kinds of leaves throughout the year. Some will be low-lying like that, and later you'll also see some that sit atop longer stems. It relates to the time of year for the VFT.

It could be one or several plants, although I tend to lean towards several plants. Hard to tell. It looks really nice and healthy though.

If you leave it outside, it will get its own insects, unless your indoor home also has a plentiful supply. Inside, you can read up on how or what to feed it, if you want to give it some nutrients, but otherwise, it can do OK on sunlight only (meaning you do not explicitly have to feed it).

That's not one plant, try repotting it, it'll be happyer, i know this because some leaves clump around a few points and each point has a bulb and each bulb as around 7+ traps

These grow in the open in nature, in addition to special soil conditions what they want is quite bright light and adequate humidity. Like many other "carnivorous" plants the insect eating makes up for the significantly nutrient deficient soils of their native habitat.
