And i have tried to edit the font size at /plugins/bbpress/templates/default/css/bbpress.css

but i dont see the font changes at all.

I am trying very hard to edit:

1) reply font size
2) Author name’s font size
3) Avatar size
4) alternate post background colour

Thanks guys for helping.

It is usually recommended to not edit the core plugin files. Use a custom css plugin and add some of these styles and customize it to how you want it.

1.

.bbp-forum-content p,
.bbp-topic-content p, 
.bbp-reply-content p {
    font-size: 16px;
}

2.

.bbp-topic-author a.bbp-author-name,
.bbp-reply-author a.bbp-author-name {
    font-size: 14px;
}

3.

Depends on what Avatars exactly? Plus CSS is not the best way to adjust this.

#bbpress-forums div.bbp-forum-author img.avatar,
#bbpress-forums div.bbp-topic-author img.avatar,
#bbpress-forums div.bbp-reply-author img.avatar {
    border: none;
    max-width: 80px;
    padding: 0;
    margin: 12px auto 0 auto;
    float: none;
}

#bbpress-forums div.even,
#bbpress-forums ul.even {
	background-color: #fff;
}

#bbpress-forums div.odd,
#bbpress-forums ul.odd {
	background-color: #fbfbfb;
}
