Every person can learn to sing, and most people learn to improve their singing by taking voice lessons with a qualified teacher. If you are asking "will I ever be able to sing as high as Fergie," it is very unlikely, since men cannot usually reach the highest notes women can; however, if you listen to men who sing in the countertenor range (Daniel Taylor, for example), some of them sing very, very high indeed.

If you are asking "will I ever be able to sing higher than I can now," the answer is, of course, yes – with training and practice. Will you ever sound like Fergie? Not likely, because if you sing, you should sing with your own voice. Otherwise, if you try to sound like her, you will have to force your voice to make some very unnatural sounds, which could be damaging to your vocal cords. In any case, keep singing, and if you can, find a teacher in your area. Best of luck!

I suggest you learn the notes on a keyboard, and sing along with them. That way you can hear both voices and if you're hitting the correct note. You can also use this to improve your range (how high or low pitched you can go) if you just keep practising. When you sing, also take deep breaths from your stomach, stand up straight and don't whisper. Also doing voice excercises can help by getting your voice warmed up (singing along a note at a time on a keyboard, humming up and down, just little fun things that get your voice ready).

Most people do too much and try to sound amazing when they first sing but most times, they don't do too well. Take things one step at a time. First, get the notes right. Then add a little bit of vibrato (the vibration in people's voices that make it go a bit "wobbly"), then a little more, and just listen to the original song and hear every part that the voice makes and try to sing along afterwards and in little sections.

Hope that helps!

Most anyone can learn to sing, though starting early is very helpful and you can't necessarily expect your voice to sound like this or that singer. Each voice is unique and stressing out because it's not what you think people find beautiful is a lot like stressing out because your booty's too big. It's possible, to a degree, to change it but it's healthier overall to accept it as your own way of being.

You can take lessons, sure, but it's hardly the only way.

One really great way to learn to sing is to join a choir. Community groups, churches, even community colleges have choirs that are almost always hungry for members. If you cup your ear, like holding a seashell to it, you can hear yourself better and learn to adjust to sound like you want to.

Like with most everything else, there's no "miracle cure" but if you are willing to feel a bit silly at first and understand that we've all been there, a choir can be a lot of fun and a great learning experience. 🙂 Good luck!
