Honestly, most of the time when checking the horizon, the background vertical references are used, and they are too small to for any tool to be used reliably (and if you magnify enough, pretty much everything will look straight, since the whole image is based on square pixels). In the rare case you're trying to measure the actual horizon, any tool that creates a perfectly straight line can be used. I use the cropping tool myself in that situation.

How to determine whether a photo is suffering from a particular color cast or not?
Is there any particular software or tool to understand that? How to remove color cast?
I'm not aware of any software that can actually detect a color cast. For me though, the best way to see is just visually. If the color looks unnatural to my eyes, I'll adjust the color with the Color Balance tool in Photoshop, and add more of whatever color cancels out the existing cast. The equalize tool in Photoshop sometimes helps detect a cast too.
Ex: If I have a shot that looks cyan, I'll either add more red with color balance in Photoshop or move the cyan slider to -100 in Lightroom. Or sometimes do both.

Thanks in advance.
Color casts can be removed via PS with color or WB adjustments, but determining whether there is a cast is a bit trickier. You can try using the RGB histogram, but I usually rely on just my eyes.
