I would like to ask on the processes that one follows when you want to make an invest? Also must you be having a lot of money to start investing?and which is the least amount of money you can invest e.g.. In shares

Depends on what you want to invest in, and with who. With discount brokers you can setup an account with very little in funds.

If investing is something you want to do, then educate yourself with the vocabulary of what you want to invest in. If it's stocks, then learn what mutual funds are, bonds, nasdaq, etc...
If it's real estate, which will bring you the most money, then learn about interest rates, flipping, your credit score, etc... That's how you start.

Also, check Vanguard's website. They have cheap fees and can do most anything.
A certificate of deposit (CD) is a good start for a lump sum while your mulling over options.

Very sound advice.

This is also helpful.
