I don't know if they intended each destroyer squadron to completely fill the blank pennant spaces. Just a note. But if they want to do that, they need to go past the 25th 052D. They are going to have to build more. A lot more. Maybe they will save the extra spaces for 052E?
You can make your conclusion from the listings.
2nd Destroyer Squadron. Located in Zhanjiang, Guangzhou.
161 Hohhot. This is 2nd block 052D. Some refinements over 1st block 052D.
162 052DL Huainan in trials in Jiangnan
163 052DL Guilin currently fitting in Dalian
164 052DL currently fitting in Jiangnan
165 Recently Retired Luda named Zhanjiang
166 Recently Retired Luda named Zhuhai
167 051B Shenzhen, refit active
168 052B Guanzhou, 052B currently in MLU, inactive
169 052B Wuhan, active
Five here if you are assuming replacement of older ships, but IMO 167, 168 and 169 still have more years, and 168 and 169 will get MLU. That leaves this squadron with two spares, 165 and 166 after the retired Ludas. The names Zhanjiang and Zhuhai will be open for adoption by future destroyer.
9th Destroyer Squadron. Located Sansha, Hainan.
170 052C Lanzhou
171 052C Haikou
172 052D Kunming
173 052D Changsha
174 052D Hefei
175 052D Yinchuan
176 to 179 empty
This squadron is the first to get 052C, and the first to get 052D. The four 052D ever made went as an entire group to the 9th. Since then, they didn't get any new ship. None of the remaining 052DL currently being made is slated for this squadron. So what gives? I suspect this group is going to get 055 in the future instead.
3rd Destroyer Squadon, ESF.
131 052D Taiyuan. First 052D of this group, a second block construction.
132 052DL Suzhou. 052DL currently in trials in Jiangnan.
133 052DL currently being fitted in Jiangnan
134 052DL currently being fitted in Jiangnan
135 Empty
136 956E Hanzhou refitted
137 956E Fuzhou refitted
138 956EM Taizhou in service
139 956EM Ningbo in service
5 more destroyers needed here if you want to fill all the numbers and replace the Sovremenny. But I don't think the Sovremenny will disappear soon.
6th Destroyer Squadron ESF
150 052C Changchun
151 052C Zhengzhou
152 052C Jinan
153 052C Xian

155 052D Nanjing
156 052DL Ningbo
157 052DL Nanning, currently in trials in Jiangnan
158 empty
159 empty
1st Destroyer Squadron
101 055 Nanchang
102 to 110 went to Anshan and Luda class destroyers, retired. 102 to 108 reserved for 055?
111 not used

114 not used
115 051C Shenyang
116 051C Shijizhuang
