How to minimize Jquery import instances on my site?

Hi friends
 
I am developing a site for my client in wordpress. According to clients needs I have to add 6-7 jquery instances into a site. means I need to import jquery.js file for each of JQuery effect such as menu, slider, scrooler, tabs, buttons into a site. Because of this site loading time is affected and I need to use noconflict() function to make jquery variable separate for each of JQuery effect.
 
I need help to improve site loading time by minimizing importing of jquery.js file. but I need to keep all the effect as before.
 
Please reply me soon.
