    <div class="dot"></div>
    <div class="dot"></div>
    <div class="dot"></div>
    <div class="dot"></div>
    <div class="dot"></div>
</div>

2. 两排竖三

.six-dots-column {
    display: flex;
    flex-direction: column;
    flex-wrap: wrap;
    align-content: space-between;
    justify-content: space-between;
}
<div class="touzi six-dots-column">
    <div class="dot"></div>
    <div class="dot"></div>
    <div class="dot"></div>
    <div class="dot"></div>
