Kara:
Kara debuted back in 2007 with 4 members: Gyuri, Seung-Yeon, Sung-hee, and Nicole.
In 2008, the lead vocalist, Sung-hee leaves Kara due to her parents pressure. It's been said that they were upset because her school efficiency was decreasing. Then DSP media decided to rebrand Kara as a 5-member girl group with the addition of two new members, this members end up being Goo Hara and Kang Jiyoung.
So, now Kara only has 3 members left. Gyuri and Seungyeon are the only ones that have been in the grup since its debut.
Wonder Girls:
It feels like it has been ages since the Wonder Girls were the biggest girl group in South Korea, a lot has happened to them since their debut:
2007: In 2007, the Wonder Girls debuted with Irony, there were 5 members: Sunye, Yeun (Yenny), Hyuna (yes, 4minute's Hyuna), Sunmi and Sohee. On June, Hyuna left the group due to health problems (gastroenteritis and fainting spells). She was replaced by Good Entertainment trainee, Yubin.
In 2013, Ahreum confirmed that she would be leaving the group to pursue her solo career. But, as well as with Hwayoung, there were several rumours around her saying that she doesn't has mental stability. This rumours came from her weird Instagram pictures, and because she said she can see ghosts.

Sohee
Are the Wonder Girls over now that Sohee has signed with BH entertainment and Sunye is going to do volunteer work in Haità for five years? BH said that Sohee can promote as a WG without any problems, but what's going on with Sunye? She is the leader but now she is married and has a baby. Well, at least we can be thankful for all those amazing songs the WG gave us!
T-ara:
T-ara released their first song for the drama "Cinderella Man" before debuting as a five-member group (Jiae, Jiwon, Eunjung, Hyomin and Jiyeon). Both Jiae and Jiwon withdrew from the group before debuting. In July 2009, T-ara debuted with Hyomin, Eunjung and Jiyeon with the addition of Soyeon, Qri and Boram; making them a six-member group. (coincidentally, it's the same line-up they have now).
On December 2010, T-ara added Hwayoung as their new member.
In 2012, their agency announced that two new members, Ahreum and Dani, wew going to join T-ara, to make them a 9-member group. Ahreum became the maknae because Dani was too young to join the group at that time.
Hwayoung's departure was announced in the middle of their "Day by Day" promotions, which were temporarily stopped. The official version given by Core Contents Media was that there were several complaints about Hwayoung, but there were huge rumours about the other members bullying her. If it's true or not, is still a mistery; but some of the rumours had been already confirmed to be lies made by haters. This rumour greatly impacted T-ara's position as one of the main K-POP girl groups in Korea.

A Pink:
A Pink debuted in 2011 with seven members: Son Naeun, Park Chorong, Oh Hayoung, Jung Eunji, Hong Yookyung, Yoon Bomi and Kim Namjoo.
In April 2013, Yookyung left the group to focus on studying or that's what A Cube said, but as well as in T-ara, there were rumours about bullying but it didn't affect A Pink that much because they weren't big back then.
